Abstract: An apparatus intended for generating process heat for a packaging arrangement and can be operated using an energy source which can only be regulated to a limited extent, if at all. For this purpose, the apparatus contains a heat-transfer medium and a heat accumulator.

Abstract: A swimming device for a swimmer or diver is described, which has a monofin, a power transfer element for moving the monofin using muscle power, and a fastening device for fastening the power transfer element to the lower legs of the swimmer. The power transfer element has a lower leg section, a foot section, and a fin section. In order to achieve the highest possible propulsion in the water with the lowest possible use of force, the power transfer element flows dynamically, in cross section in the X-Z level with a longer Z axis and short X-axis.

Abstract: A swimming device (1, 10, 30) for a swimmer or diver (2) is described, which has a monofin (3), a power transfer element (4, 14) for moving the monofin (3) using muscle power, and a fastening device (5, 15) for fastening the power transfer element (4, 14) to the lower legs of the swimmer (2), whereby the power transfer element (4, 14) comprises a lower leg section, a foot section, and fin section. In order to achieve the highest possible propulsion in the water with the lowest possible use of force, the power transfer element (4, 14) is mainly designed flow dynamically, in cross section in the X-Z level with a longer Z axis and short X-axis.

Abstract: A device for grouping individually packaged goods which are fed in a substantially closed stream by the means of conveyance along a transport plane, and grouped by at least one divider finger which can be introduced from below transversely to the transport plane into the stream along the conveyance direction, where, for the at least one divider finger, a motor drive provided which is capable of carrying out in a free and adjustable manner a movement of the at least one divider finger transversely to the transport plane (z-direction) independently of the movement along the conveyance direction (y-direction) and vise versa.
